In contrast to metallic alloys, each material retains its separate chemical, physical, and mechanical properties. the two constituents are a reinforcement and a matrix. the main advantages of Composite ma-terials are their high strength and stiffness, com-bined with low density, when compared with bulk Materials , allowing for a weight reduction in the finished reinforcing phase provides the strength and stiffness.
torted into a parallelogram, a shear strain g xy is induced as a result of coupling between the axial strains e xx and e yy. If the fibers are aligned parallel to the direc-tion of applied stress, as in the lower portion of Fig. 1.7 Shear coupling in a 45° ply. Source: Ref 1
